A ginger snap, ginger nut, or ginger biscuit is a globally popular biscuit based snack food, flavoured with ginger. Ginger snaps are flavoured with powdered ginger and a variety of other spices, most commonly cinnamon, molasses[1] and nutmeg.[2] There are many recipes.[3] The brittle ginger nut style is a commercial version of the traditional fairings once made for market fairs now represented only by the Cornish fairing.

Ginger nuts are the most popular biscuit in New Zealand, normally attributed to its tough texture which can withstand dunking into liquid. Leading biscuit manufacturer Griffin's estimates 60 million of them are produced each year. This has become the title of a book, 60 Million Gingernuts, a chronicle of New Zealand records.[5][6][7] In Australia, Arnott's Biscuits manufactures four different regional varieties of ginger nut to suit the tastes of people in different states.[8]

In the United States, the usual term is ginger snaps, and they are generally round drop cookies, usually between 3 mm (1/8-inch) and 6 mm (1/4-inch) thick, with prominent cracks in the top surface.

Scandinavian ginger nuts, also called ginger bread or "brunkage" in Danish (literally meaning "brown biscuits"), pepparkakor in Swedish, piparkakut in Finnish, piparkūkas in Latvian, piparkoogid in Estonian and pepperkaker in Norwegian (literally, pepper cookies), are rolled quite thin (often under 3 mm (1/8-inch) thick), and cut into shapes; they are smooth and are usually much thinner and hence crisper (and in some cases, more strongly flavoured) than most global varieties. Cloves, cinnamon and cardamom are important ingredients of these, and the actual ginger taste is not prominent. Allspice was used formerly to season ginger biscuits, but cloves replaced it later.[9]
